During 2020-2021，the Conservative Party ruled under the dual pressure of the COVID-19 pandemic control and the UK-EU trade deal negotiations. Despite the public discontent and intraparty disparities caused by some of its policies，the Conservative Party secured more seats in the 2021 local elections thanks to the conclusion of a post-Brexit trade deal with the EU and the successful rollout of the vaccination program. The Labour Party criticized the government over issues like COVID-19 pandemic response，economic recovery and trade deal negotiations，but failed to propose a well-defined Labour route of governing. The Labour Party intentionally blurred the ideological differences between itself and the Conservative Party，which to some extent，led to its defeat in the local elections. The Scottish Nationalist Party reproposed a second referendum on Scottish independence，and was very much likely to push for it by coalition with the Green Party after the 2021 Scottish Parliament election. With Brexit being settled，the Liberal Democratic Party weakened its pro-EU position and won more seats in the local elections. Using the potential party coalition as a bargaining chip，the Green Party tried to shape the policies of the Scottish Nationalist Government in a bid to achieve its climate and environment policy goals.
